Rectangular blocks are inserted and connected to both the left end and the right end of the frame body. A support plate is jointly arranged between the left inner wall and the right inner wall of the frame body. A grid box body which can move up and down is arranged inside the frame body. Fixed components are arranged inside both of the two rectangular blocks, and the two fixed components are symmetrically distributed left and right. Fixed slots are opened at both the left end and the right end of the grid box body. An inclined surface is jointly arranged between the lower end and the left end and the right end of the grid box body.

[0007] Preferably, rectangular grooves are opened inside both of the two rectangular blocks, and circular grooves are opened on the inner walls of the two rectangular grooves.

[0008] Preferably, the fixed component includes a trapezoidal block which is arranged in the rectangular groove. A circular plate is fixedly sleeved on the outer surface of the trapezoidal block. A first spring is installed at one end of the circular plate away from the grid box body, and the first spring is movably sleeved on the trapezoidal block. A pull ring is installed at one end of the trapezoidal block away from the grid box body, and the trapezoidal block extends into the fixed slot.

[0009] Preferably, the trapezoidal block is matched with the inclined surface.

[0010] Preferably, positioning grooves are provided at both the left end and the right end of the frame body, fixing ears are installed at both the left end and the right end of the cage body, and the left and right fixing ears are respectively arranged in the two positioning grooves.

[0011] Preferably, the left end and the right end of the support plate are respectively movably connected to the left inner wall and the right inner wall of the frame body. Second springs are installed at the four corners of the lower end of the support plate, and a T-shaped groove is provided in the middle of the lower end of the support plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By setting the fixing component and the inclined surface to cooperate with each other, the cage body can be quickly fixed. When in use, the cage body is placed into the frame body and moved downward. When the inclined surface contacts the trapezoidal block and the cage body continues to move downward, the trapezoidal block is squeezed and completely enters the rectangular groove. When the cage body contacts the support plate, the trapezoidal block enters the fixing groove under the elastic force of the first spring, and the fixing of the cage body can be completed. The operation is simple, without the need to use a large number of bolts for fixing, reducing the operation difficulty and installation time, reducing the safety risk, and bringing convenience to workers.

[0015] 2. By setting the T-shaped groove, the fixing rod, the abutting plate and the second spring to cooperate with each other, the cage body can be conveniently disassembled. When disassembly and maintenance are required, the fixing rod is pulled outwards, so that the two abutting plates are far away from the T-shaped groove and the frame body, and the second spring is no longer restricted. Then, the two pull rings are pulled outwards, so that the trapezoidal block is far away from the fixing groove. The second spring drives the support plate and the cage body to move upward a certain distance through its own elastic force, so that the fixing groove is far away from the vicinity of the trapezoidal block, and the cage body can be taken out of the frame body. The operation is simple and the operation time is short, further improving the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Such as Figures 1 - 5As shown in the figure, a grid-connected box for a photovoltaic power station that is easy to install, includes a frame body 3. Two clamps 2 are installed at the rear end of the frame body 3. Rectangular blocks 6 are inserted and connected to both the left end and the right end of the frame body 3. A support plate 11 is jointly arranged between the left inner wall and the right inner wall of the frame body 3. A net box main body 5 that can move up and down is arranged inside the frame body 3. During installation, the clamps 2 are fixed on the electric pole 1, and the net box main body 5 is fixed inside the frame body 3 through multiple groups of bolts. The circuits on the net box main body 5 are connected to the photovoltaic power station. However, using multiple groups of bolts to fix the net box main body 5 increases the complexity and time of installation for workers working at heights and increases the safety risk.

[0026] To solve the above problems, the net box main body 5 is fixed through the joint cooperation of a fixing component 7 and an inclined surface 12. The specific structure is as follows: Fixing components 7 are arranged inside both of the two rectangular blocks 6. The two fixing components 7 are symmetrically distributed left and right. Fixing grooves 8 are opened at both the left end and the right end of the net box main body 5. Inclined surfaces 12 are jointly arranged between the lower end of the net box main body 5 and its left end and right end. Rectangular grooves 61 are opened inside both of the two rectangular blocks 6. Circular grooves 62 are opened on the inner walls of the two rectangular grooves 61. The fixing component 7 includes a trapezoidal block 71. The trapezoidal block 71 is arranged inside the rectangular groove 61. A circular plate 72 is fixedly sleeved on the outer surface of the trapezoidal block 71. One end of the circular plate 72 away from the net box main body 5 is installed with a first spring 73. The first spring 73 is movably sleeved on the trapezoidal block 71. A pull ring 74 is installed at one end of the trapezoidal block 71 away from the net box main body 5. The trapezoidal block 71 extends into the fixing groove 8. The trapezoidal block 71 cooperates with the inclined surface 12. During use, the net box main body 5 is placed into the frame body 3. The net box main body 5 is moved downward. When the inclined surface 12 contacts the trapezoidal block 71 and the net box main body 5 continues to move downward, the trapezoidal block 71 is squeezed and completely enters the rectangular groove 61, and the first spring 73 is compressed. When the net box main body 5 contacts the support plate 11, the trapezoidal block 71 enters the fixing groove 8 under the elastic force of the first spring 73, and the fixing of the net box main body 5 can be completed. The operation is simple, without the need to use a large number of bolts for fixing, reducing the operation difficulty and installation time, and reducing the safety risk, bringing convenience to the workers.

[0027] In order to quickly align the fixing groove 8 with the trapezoidal block 71, positioning grooves 4 are opened at both the left end and the right end of the frame body 3. Fixing ears 10 are installed at both the left end and the right end of the net box main body 5. The fixing ears 10 are used to facilitate the subsequent installation of the net box main body 5 on the wall. The left and right fixing ears 10 are respectively arranged inside the two positioning grooves 4. During installation, the fixing ears 10 are inserted into the positioning grooves 4, and the moving range of the net box main body 5 can be limited, making the fixing groove 8 move in the direction of the trapezoidal block 71.

[0028] In addition, when disassembling, it is necessary to pull the pull rings 74 with both hands to move the trapezoidal block 71 away from the fixing groove 8, and then push the cage body 5 upward. In order to be able to automatically push the cage body 5 to move, the left end and the right end of the support plate 11 are respectively movably connected to the left inner wall and the right inner wall of the frame body 3. Four second springs 16 are installed at the four corners of the lower end of the support plate 11. In the initial state, the second springs 16 are in a compressed state. A T-shaped groove 13 is formed in the middle of the lower end of the support plate 11. The lower ends of the four second springs 16 are fixedly connected to the lower inner wall of the frame body 3. A through groove 9 is formed in the lower end of the frame body 3. A fixing rod 14 is arranged in the through groove 9. The lower end and the upper end of the fixing rod 14 are both provided with a pressing plate 15. The upper pressing plate 15 is arranged in the T-shaped groove 13, and the lower pressing plate 15 is in movable contact with the lower end of the frame body 3. Pull out the fixing rod 14 outward to make the two pressing plates 15 away from the T-shaped groove 13 and the frame body 3. The second springs 16 are no longer restricted. Then pull the two pull rings 74 outward to make the trapezoidal block 71 away from the fixing groove 8. The second springs 16 drive the support plate 11 and the cage body 5 to move upward by a certain distance through their own elastic force, so that the fixing groove 8 is away from the vicinity of the trapezoidal block 71, and the cage body 5 can be taken out of the frame body 3. The operation is simple and the operation time is short, which further improves the work efficiency.
